A Case of a Lethal Diquat Ingestion in a Toddler

Abstract Background Diquat is an herbicide that may cause rapid and profound systemic toxicity. It can cause multisystem organ failure, primarily via its effects on the gastrointestinal, renal, cardiovascular, and central nervous systems. Case fatality rates as high as 43% have been reported. There is a paucity of pediatric literature on diquat poisoning, and in this article, we will discuss an unfortunate pediatric case that highlights the severity of diquat toxicity. Case Report We present the case of a child who ingested diquat, which led to multisystem organ failure and death. Why Should an Emergency Physician Be Aware of This? Clinicians should be aware of this herbicide's potential for significant morbidity and mortality, especially in children, in whom small quantities can be lethal. It is important that emergency physicians are aware of the significant toxicity of diquat and provide early gastric decontamination, as it is the only proven therapeutic strategy.
